 ### Instructions
 
-Write a class `DateFormatter` that has three private attributes: 
-* `date`: the date to be formatted (as a date).
-* `format`: the format to convert the date to.
-* `formattedDate`: contains the date converted into the given format.
+Write a class `DateFormatter` that has three private attributes:
+
+- `date`: the date to be formatted (as a date).
+- `format`: the format to convert the date to.
+- `formattedDate`: contains the date converted into the given format.
 
 Create getters for all the attributes and setters for `date` and `format`. The conversion should happen when you set the `format` or the `date`. If the `format` is not correct, the conversion shouldn't happen. Additionally, create methods to output the date in the specified `format`, and constructors with only the `date`, with `date` and `format`, and a default constructor.
 
 #### The accepted date formats are:

 - `DD/MM/YYYY`
